Metrolinx is constructing twin tunnels less than three metres directly underneath 21 live traffic lanes on Highways 401 and 409. Given that this is one of the busiest sections of highway in North America, digging two 180-metre-long tunnels (approximately) is a unique challenge.

With major construction underway, communities are one step closer to more service along the Kitchener corridor.

The Highway 401 and 409 Rail Tunnels project is part of the GO Expansion program, which will transform the Kitchener line from a rush hour commuter service to a more convenient transit experience with frequent, two-way, all-day rail service.

As the region continues to grow, more trips along the Kitchener line will open up opportunities for those connecting to jobs, family and what matters most – helping them get to where they need to go better, faster, easier.

Franca, Mike, and Josh, will provide an overview of the project and discuss methodology, key milestones, and challenges.
